Abstract
Phosphine-free palladium–salen complexes, N, N′-bis (salicylidene)-ethylenediamino- palladium and N, N′-bis (salicylidene)-1, 2-phenylenediamino palladium, are found to be highly active catalysts for the Heck olefination of aryl iodides and Suzuki reaction of aryl iodides and bromides giving excellent yields (70–90%) of products under aerobic conditions, in short reaction times (10–60min).
